PIXEL_SCALE was broken in that last release (just in the compiler), and a few other misc. fixes are in. Pretty close to closing out 511 as final.

[edit]
Rereleased due to a new bug in some error checking that got added for Dream Maker. This only impacts the compiler. If you downloaded earlier, you may want to download and install again if you see any bogus compiler errors.

[edit]
Re-release because the server-side fix was not implemented correctly. If you downloaded 511.1384 earlier in the day you might want to download again. This will only affect you if you're hosting a server for a game with a large map undergoing a lot of changes, and only in rare cases. If you never this problem with past versions, you probably don't need to re-download.
